Kaposi sarcoma in a patient with giant cell arteritis.

Kaposi sarcoma usually occurs in immunosuppressed patients. A classic type has been reported in elderly men of Jewish and Mediterranean origin. We report a case of an elderly woman with giant cell arteritis (GCA) who developed Kaposi sarcoma while on a double blind trial for GCA with an anti-tumor-necrosis-factor medication.

Blueberry muffin rash as a presentation of alveolar cell rhabdomyosarcoma in a neonate.

Soft tissue sarcomas of childhood continue to present problems with pathologic diagnosis, staging and treatment. Rhabdomyosarcoma, the most common soft tissue sarcoma, represents 4-8% of all malignant solid tumours in children. We report a case of congenital alveolar rhabdomyosarcoma who presented with "blueberry muffin"-like rash.

Vasculitis by organ systems.

Systemic vasculitides, hitherto thought to be a rare clinical entity, are now rarely considered to be an uncommon disorder and patients are often seen between several departments, suffering from a non-infectious systemic disease with multi-organ involvement. Systemic vasculitis not only poses a major management problem but also has a significant impact on healthcare resources. The clinical outcome of a vasculitic illness depends on a number of factors, such as aetiology of the vasculitic process, site, size and number of blood vessels affected, duration and severity of the disease and also the complications associated with the disease or its therapy.
